Abstract

1. A clutch-operated shift lock for fluid-operated manual transmissions (7), particularly for motor vehicles, comprising a clutch slave cylinder, preferably a clutch servo unit (15), acting in response to the actuation of a clutch pedal (25) for engaging and disengaging an input clutch (1) allocated to the fluidoperable manual transmission (7) and for engaging and disengaging a shift device which can be operated by the clutch servo unit (15) and which controls the supply of fluid to the shift lock as a function of the clutch in such a way that a gearshift is only possible when the clutch is fully disengaged, wherein the shift device consists of a shift valve (17) which is located in the axial projection of the piston rod (29) of the clutch servo unit (15), and wherein a frictionally engaged driver (81, 85) connects the piston rod (29) to the shift valve (17) in such a way that the shift valve controls the supply of fluid to the shift lock as a function of the movements of the piston rod (29).
